Precaution for Technicians Using Medical Electric

INFOID:0000000010121649

OPERATION PROHIBITION

WARNING:

• Parts with strong magnet is used in this vehicle.

• Technicians using a medical electric device such as pacemaker must never perform operation on the

vehicle, as magnetic field can affect the device function by approaching to such parts.

NORMAL CHARGE PRECAUTION

WARNING:

• If a technician uses a medical electric device such as an implantable cardiac pacemaker or an

implantable cardioverter defibrillator, the possible effects on the devices must be checked with the

device manufacturer before starting the charge operation.

• As radiated electromagnetic wave generated by PDM (Power Delivery Module) at normal charge

operation may affect medical electric devices, a technician using a medical electric device such as

implantable cardiac pacemaker or an implantable cardioverter defibrillator must not approach motor

room [PDM (Power Delivery Module)] at the hood-opened condition during normal charge operation.

PRECAUTION AT TELEMATICS SYSTEM OPERATION

WARNING:

• If a technician uses implantable cardiac pacemaker or implantable cardioverter defibrillator (ICD),

avoid the device implanted part from approaching within approximately 220 mm (8.66 in) from inte-

rior/exterior antenna.

• The electromagnetic wave of TCU might affect the function of the implantable cardiac pacemaker or

the implantable cardioverter defibrillator (ICD), when using the service, etc.

• If a technician uses other medical electric devices than implantable cardiac pacemaker or implant-

able cardioverter defibrillator (ICD), the electromagnetic wave of TCU might affect the function of the

device. The possible effects on the devices must be checked with the device manufacturer before

TCU use.

PRECAUTION AT INTELLIGENT KEY SYSTEM OPERATION

WARNING:

• If a technician uses implantable cardiac pacemaker or implantable cardioverter defibrillator (ICD),

avoid the device implanted part from approaching within approximately 220 mm (8.66 in) from inte-

rior/exterior antenna.

• The electromagnetic wave of Intelligent Key might affect the function of the implantable cardiac

pacemaker or the implantable cardioverter defibrillator (ICD), at door operation, at each request

switch operation, or at engine starting.

• If a technician uses other medical electric devices than implantable cardiac pacemaker or implant-

able cardioverter defibrillator (ICD), the electromagnetic wave of Intelligent Key might affect the

function of the device. The possible effects on the devices must be checked with the device manu-

facturer before Intelligent Key use.

Point to Be Checked Before Starting Maintenance Work

INFOID:0000000010121650

The high voltage system may starts automatically. It is required to check that the timer air conditioner

and timer charge (during EVSE connection) are not set before starting maintenance work.

NOTE:

If the timer air conditioner or timer charge (during EVSE connection) is set, the high voltage system starts

automatically even when the power switch is in OFF state.

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"

INFOID:0000000010121651

The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along

with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain

types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS

PRECAUTIONS

FAX

system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front

air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.

Information necessary to service the system safely is included in the SR and SB section of this Service Man-

ual.

WARNING:

• To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in

the event of a collision which would result in air bag inflation, all maintenance must be performed by

an authorized NISSAN/INFINITI dealer.

• Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal

injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag

Module, see the SR section.

• Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this

Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or har-

ness connectors.

PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS

WARNING:

• When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Igni-

tion ON or engine running, DO NOT use air or electric power tools or strike near the sensor(s) with a

hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing

serious injury.

• When using air or electric power tools or hammers, always switch the Ignition OFF, disconnect the

battery and wait at least three minutes before performing any service.

Precaution for Removing 12V Battery

INFOID:0000000010121652

1. Check that EVSE is not connected.

NOTE:

If EVSE is connected, the air conditioning system may be automatically activated by the timer A/C func-

tion.

2. Turn the power switch OFF

→ ON → OFF. Get out of the vehicle. Close all doors (including back door).

3. Check that the charge status indicator lamp does not blink and wait for 5 minutes or more.

NOTE:

If the battery is removed within 5 minutes after the power switch is turned OFF, plural DTCs may be

detected.

4. Remove 12V battery within 1 hour after turning the power switch OFF

→ ON → OFF.

NOTE:

• The 12V battery automatic charge control may start automatically even when the power switch is in

OFF state.

• Once the power switch is turned ON

→ OFF, the 12V battery automatic charge control does not start for

approximately 1 hour.

CAUTION:

• After all doors (including back door) are closed, if a door (including back door) is opened before

battery terminals are disconnected, start over from Step 1.

• After turning the power switch OFF, if “Remote A/C” is activated by user operation, stop the air

conditioner and start over from Step 1.

Precautions for Drive Shaft

INFOID:0000000010121653

Observe the following precautions when disassembling and assembling drive shaft.

• Never disassemble joint sub-assembly because it is non-overhaul parts.

• Perform work in a location which is as dust-free as possible.

• Clean the parts, before disassembling and assembling.

• Prevent the entry of foreign objects during disassembly of the service location.

• Reassemble disassembled parts carefully in the correct order. If work is interrupted, a clean cover must be

placed over parts.

• Use paper waste. Fabric shop cloths must not be used because of the danger of lint adhering to parts.

• Clean disassembled parts (except for rubber parts) with kerosene which shall be removed by blowing with

air or wiping with paper waste.
